MPROVEMENT IN HYDRANTS.

To all 'wlwmtt mag/concern:

Be it known-that I, CHARLES E. FRAziER, of the city and county of Baltimore, in the State of Maryland, have invented a new and improved Hydrant; and I do hereby' declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and to 'the letters of reference marked thereon, in which like parts are indicated by like letters in the several figures;

flhenature of my invention consists in constructing a simple, adjustable, economical, non-wasting, and nonfreezing hydrant, to be hereafter more fully described, in order that those skilled in the art should be able to make and use the saine.`

In the drawings- Figure l represents a vertical section through vmy hydrant, as closed;

Figure 2, a partial section ot same, the valvebeing open, or raised;

Figure 3 is also a partial section of the lower part of my hydrant, as modified, the valve being closed; whilst Figure 4 is a still ymore limited section of said modication, the valve being open.

Figure 5 is a top ew of a pertora'ated nut, as shown in section in 3, whilst Figure (i is a section, on line ci-b, iig. 3.

'A, iig. l, is a vertical section of my hydrant-box, having a metallic or other suitable cap, B. Working on or in this (so as to be capable of being rotated) is a metallic or other durable tube, C, the same being slotted, and in which slot, o', the handle D works up and down. A side recess at the top, and one at the bottom of this slot, keep the handle in the position desired.

The handle D is secured to tube C in any suitable manner, as seen img. 1, and it passes through a rod, E, which is perforated as at e, and this rod extends down to a hollow metallic piston, b, having a lip, e c. Between this lip, or circular ange, and a ring, (I, is compressed a leather or other suitable washer, e, bearing against the inside of chamber F, which is open at the top. The ring d has slots in it which pass over lugs l', on the outside of the pistoni), and by turning the ring under the lugs, the packing or washer e is held rm. The piston 1) vis shown in iig. 1in a raise`d position, leaving a space, f, below it for the water in dischargepipe G to fall back into when the hydrant is shut off, thuspreventing any freezing. v

H is a hollow screw, the top of which is soA shaped thatl it can be rotated by means of b, the rod E, and handle D.

Passing upward, through H, is the valve-stem l, supported or held by a pin, g, at the top, and at the lower end is secured the valve 7i, which maybe confined in a cylindrical or other-shaped cup, and which is shown in tig. l as pressed or Vscrewed domi upon its seat, the top of supply-pipe K. The valve is shown Vsecured by a screw.v

The operation is as follows:

In iig.l l, the hydrant is shown in its normal or closed position, the supply-pipe G 'supposed to be empty, and the shut-oilwater having fallen back into the space f, in chamber F, below piston b. lo open it, the handle D is lowered to the bottom of the slot c', in top C, which forces the water below the piston into the supply-pipe G, through connection-pipe t; then, by pushing the handle in a proper direction, laterally, rotating the top C, and the hollow screwl H, this latter will be raised, and, with it, the valve h, thus permitting a how of water out from under it, into and up through the dischargepipe. By reversing the motion of handle D, the valve is screwed down upon the top of supply-pipe K, which shuts oli the water, and then, by raising the handle to the top of its slot, c', the piston is raised, andthe water in G falls back into the space f, underneath l). The handle should rest in the upper side recess, at the top of c. f

The rotation of piston-rod E is limit-ed by a pin, p, projecting from it, or tube C, coming in Contact with another underneath the cap' B, as seen in iig. l.

Having thus described my invention,

What l claim new, and desire to secure by Letters Patent ofthe United States, is-

1. The cap or top B C, constructed and operated in the manner substantially asshown and described, and

for the purpose set forth.

2. The combination ofthe hollow screw H, and the valve-stem l, arranged, construe ed, and operated in the manner substantially as shown and described, and for the pmpose set forth.

3. The combination of chamber F, screw H, ,rod I, and hollow piston b, arranged, constructed, and operated in the manner substantially as shown and described, and forthe purpose set forth.

CHARLES E. FRAZIER.
